Test Description of Commands
T0
1
Runs customer mode system exerciser. No loopback
connectors are needed. Removable media must be loaded
in the RX23 disk drive for the exerciser to recognize the
drive. The TZ30 does not require media to be loaded. The
exerciser tests each device once sequentially, then tests them
simultaneously, and stops when the slowest device finishes
(about 5 minutes).
T 101
1
Runs customer service mode system exerciser. Loopbacks
and removable media are required. It exercises each device
once sequentially, then exercises them simultaneously, and
stops when the slowest device finishes (about 5 to 8 minutes).
Do not stop the exerciser before it is finished.
T 102 Runs customer service mode system exerciser. Loopbacks
and removable media are required. It exercises each device
once sequentially and then exercises them simultaneously
until you press
CTRL C
to terminate the tests. Note that
the exerciser takes up to 30 seconds to stop after you press
CTRL C
. Do not stop the exerciser until every device is
exercised twice (second pass). Also, do not press the Halt
button to stop the exerciser. Once the tests are terminated,
an extended summary for only the SCSI-A and SCSI-B tests
can be displayed by pressing

T 80000106
2
Used for individual device testing. Loopbacks and removable
media are required. Runs system exerciser diagnostics on
individual devices (TEST 6 and TEST 7 are considered
individual devices even though they test several drives).
This test allows you to test individual devices by entering
the test number of the device at a second prompt. This
individual testing saves time since you do not have to wait
for all of the other devices to finish testing.
